Fantasy films are films with fantastic themes, usually involving supernatural events, magic, make-believe creatures, or exotic fantasy worlds. The genre is considered to be distinct from horror and science fiction film, although the genres do overlap. Fantasy films often have an element of magic, myth, wonder, escapism, and the extraordinary. In fantasy films, the hero often undergoes some kind of mystical experience and must ask for assistance from powerful, superhuman forces. Ancient Greek mythological figures or Arabian Nights-type narratives typically serve as a template for their storylines.
